9

#### Work Step by Step

To convert an improper fraction into a mixed number, you must first divide the numerator by the denominator. The quotient (excluding the remainder) forms the whole number part of the mixed number.
The remainder is the numerator of the fraction part of the mixed number, while the denominator is the same as the denominator of the original improper fraction.
If there is no remainder, as is the case with this fraction, the answer is a whole number with no fraction part.
$54\div6=9$
Final answer: 9
